The Distribution of Cardiac Potentials Around the Chest in One Hundred and Three Normal Men

Abstract

Chest leads farther right to V ₁ and farther left to V ₆ have been suggested, and are increasingly used, for diagnosis of right ventricular or posterior wall lesions. Normal standards are provided for the regional distribution of seven arbitrarily defined patterns and amplitudes of main deflections, in five positional groups, in 15 leads around the chest, resulting in statistical evaluation of 600 electrocardiographic items. In general, the results favor a much more conservative interpretation than has been noted in the past. Some implications to electrocardiographic theory are discussed.
